TCL script - one way audio issue

Hi,

I implemented tcl script on 2801. The script simply answer the call and plays prompt. It works fine when I'm calling from pots. When I'm calling from VoIP I have one way audio and don't hear the prompt. The phone RxCnt stays on 0. Here is part of my config:

Zdravko,

With one-way audio issues, this could definitely be related to an incorrect route on your network. In the non-working case, define which direction the audio is NOT working. For this non-working flow, be sure that every hop in your network from the Source of the stream to the Destination of the stream have a correct route.

The reason why the POTS line likely works is because it isn't routing on your internal network.

Hi,

I don't have routing issues because I tested the path with CME on both routers and I have two way audio. There is dedicated h323 voip interfaces. There is full routing between two router. I have tested that on two separate environments. I need further advices.

Zdravk,

Do you have any firewalls in place between the two endpoints? Please let me know your topology. If you have any firewall in place (PIX, ASA, IOS Firewall), be sure that you have H323 inspection enabled and see if you are seeing any packet drops/syslogs indicating the dropped traffic. If you don't have any firewalls in place, I'll defer further responses and troubleshooting ideas to my peers.
